Introduction

Jungsang Ahn is a notable inventor based in San Jose, CA (US). He has made significant contributions to the field of data storage and replication technologies. His innovative work has led to the development of a unique patent that enhances the efficiency of key-value stores.

Latest Patents

Jungsang Ahn holds a patent titled "Key-value replication with consensus protocol." This invention implements a replicated key-value store using a 'last-write-wins' consensus protocol. To improve throughput and latency in cross-data-center configurations, the system deploys a cross-cluster, learner-only member to a cluster of nodes, such as a data center. The cross-cluster, learner-only member submits key-values received at local leader members to remote clusters. Conflicts between the key-values and initial values at the remote clusters are resolved using the 'last-write-wins' consensus protocol. This innovative approach significantly enhances the performance of data replication across different locations.
